1. A weighing system for weighing items that are sequentially fed to be weighed, the weighing system comprising: (a) a weighing table constituting a preload for receiving the weight of an item to be weighed;(b) wherein the weighing table is adapted so that the item to be weighed can be fed to the weighing table and removed from the weighing table along a movement path across the weighing table; and(c) wherein a clamping device is provided above the weighing table as the preload, with which the item to be weighed, after it has been fed to the weighing table and impinges thereon with its weight, can be detachably clamped against a stop, which is fixed with respect to the weighing table, of the clamping device to enable being weighed in a clamped state. 2. The weighing system of claim 1, wherein the weighing system is further constructed for supplying the item to and removing it from the weighing table individually on a cyclical basis. 3. The weighing system of claim 1, wherein the stop is stationary in construction. 4. The weighing system of claim 1, wherein the clamping device comprises at least one clamping element, with which a clamping force component directed transversely to the movement path can be applied to the item to be weighed to clamp it against the stop. 5. The weighing system of claim 4, wherein the stop is integrally formed with the weighing table. 6. The weighing system of claim 4, further comprising a guide means adapted for guiding the clamping element and integrally formed with the weighing table. 7. The weighing system of claim 4, wherein, at a point of clamping, the movement direction of the clamping element and the path run perpendicular to a load introduction direction of a weighing cell coupled to the weighing table. 8. The weighing system of claim 7, wherein the movement direction of the clamping element, the path and a load introduction direction of the weighing cell run perpendicular to one another at a point of clamping. 9. The weighing system of claim 4, wherein the clamping element is formed in the manner of a piston and adapted to be moved via an actuating element. 10. The weighing system of claim 4, wherein the clamping element can be moved via a first end of an actuating element constructed as a connecting rod, a lever, or an articulated lever, while a second end of the actuating element is coupled to an eccentric drive element driven by a driving shaft. 11. The weighing system of claim 4, wherein the clamping element can be moved via a first end of an actuating element constructed as a connecting rod, a lever, or an articulated lever, while a second end of the actuating element is coupled to a pneumatic, electrical or electromagnetic drive unit. 12. The weighing system of claim 11, wherein the clamping element is connected via at least one spring element to the actuating element. 13. The weighing system of claim 11, wherein a sensor, is provided for direct or indirect position detection of the actuating element to determine a current position of the clamping element. 14. The weighing system of claim 4, wherein, to feed the item to be weighed onto the weighing table, a star wheel that is furnished with individual pockets and able to be rotated on a cyclical basis by predetermined angles of rotation is provided, the pockets of the star wheel being formed to accommodate one or more items to be weighed and to convey the items along the movement path. 15. The weighing system of claim 14, wherein the star wheel is constructed for simultaneous conveyance of several containers one next to another in a radial direction, each of which is to be detected by separate weighing cells, wherein the weighing cells are arranged along concentric paths one next to another in the radial direction. 16. The weighing system of claim 15, wherein the weighing cells are also arranged offset to one another in a circumferential direction. 17. The weighing system of claim 14, wherein the star wheel is adapted to be rotated backwards by a predeterminable angle of rotation after feeding the item to be weighed onto the weighing table, to release the item to be weighed on the weighing table. 18. The weighing system of claim 13, wherein the sensor comprises a proximity sensor or an encoder.
